Thank you...it was fun to accomplish a 1st project...looking forward to many, many more!
The foil, was a 'recycle' or re~purpose...the foil on the top of the plastic coffee canisters are sealed with a sturdy foil...I cut the rough rounded edges off to make a square, it cut really easy...it's about the same thickness as the Medium Cardstock, but could have probably used 1 extra pass to get the little points. It stuck very good to the mat, and glued good too.
(Folgers & Maxwell House have it for sure.)
Oh, and I didn't have rhinestones, so I embossed little black 'holes' with black embossing powder.
Thanks for the nice comments...:)
